In Tom Palmer's book "The Comedy act of Tom Palmer" he mentions using Genii Powder to make smoke appear from your pocket.

I was wondering if anybody knows about a source for this stuff.

Don't know if it's the same stuff or not.

There is also an electronic device around the dealers now which allows you to produce smoke from your pocket, it name escapes me at the moment. Maybe someone else out there knows it?
